Dengar was in Boba's Syndicate when they went to Beluga with Asajj Ventress to deliver something. As soon as they left on the Speedtrain they were attacked by Kage. Dengar and Asajj fight well on the back area, where the Kage attack first but Dengar is eventually knocked off.

On Nar Shadaa, while attempting to capture Han Solo to collect a bounty, he was thrown off a rooftop by Chewbacca along with a detonating Thermal Imploder.

Dengar was hired by Darth Vader to hunt down the Falcon alongside Bossk, Boba Fett, IG-88, 4-LOM and Zuckuss. He tracked the ship to Cloud City where he was too late to collect the bounty on Solo but served Darth Vader while the Rebels attempted escape with the aid of Lando Calrissian and the Bespin Wing Guard.
